stm32f103通用定时器pwm应用例程蜂鸣器演奏乐曲

1、stm32f103通用定时器pwm应用例程：蜂鸣器演奏乐曲一 说明：本例程是将流明lm3slib_timer.pdf文档中的例程9及例程10（pwm应用：蜂鸣器演奏乐曲），移植到stm32f103上。二流明lm3slib_timer.pdf例程9及例程10的拷贝：例程9 timer pwm应用：蜂鸣器发声如图1.1所示，为easyarm1138开发板上的蜂鸣器驱动电路。蜂鸣器类型是交流蜂鸣器，也称无源蜂鸣器，需要输入一列方波才能鸣响，发声频率等于驱动方波的频率。图1.1 蜂鸣器驱动电路程序清单1.9是timer模块16位pwm模式的一个应用，可以驱动交流蜂鸣器发声，运行后蜂鸣器以不同的频率叫两

2、声。其中buzzer.h和buzzer.c是蜂鸣器的驱动程序，仅有3个驱动函数，用起来很简捷。程序清单1.9 timer pwm应用：蜂鸣器发声文件：main.c #include systeminit.h #include buzzer.h/ 主函数（程序入口） int main(void) jtagwait(); / 防止jtag失效，重要！ clockinit(); / 时钟初始化：晶振，6mhz buzzerinit(); / 蜂鸣器初始化 buzzersound(1500); / 蜂鸣器发出1500hz声音 sysctldelay(400* (thesysclock / 3000);

8、16位pwm模式的一个应用，能驱动交流蜂鸣器演奏一首动听的乐曲化蝶（乐谱参见图1.2）。music.h和music.c是演奏乐曲的驱动程序。图1.2 乐谱化蝶简谱是大众化的音乐记谱方式，比较容易理解和掌握。我们可以把一首乐谱（score）看成是由若干个基本的音符（note）单元组成。一个音符由音名和时值组成。音名就是低音、中音、高音的1234567（唱作do re mi fa sol la si），其本质是音符的发声频率。在头文件music.h里，用l1l7、m1m7、h1h7定义了低音、中音、高音所对应的发声频率。时值是音符的发声时间长短，有全音符、二分音符、四分音符等等。音符可以后缀一个“

9、符点”，表示时值增加1/2，特殊地，二分音符加符点时用“”代替圆点。参见表1.26的描述。表1.26 常见简谱音符示例音 符 名 称 相 对 时 值 5 全音符 t 5 二分音符 t/2 5 四分音符t/4 5 八分音符 t/8 5 十六分音符 t/16 5 符点二分音符 t/2+t/4 5 符点四分音符 t/4+t/8 5 符点八分音符 t/8+t/16 在头文件music.h里定义有一个音符结构体tnote，有两个数据成员：音名mname和时值mtime。在c文件music.c里定义有一个tnote型常量数表myscore ，用来保存实际乐谱转换成tnote格式的数据。有了上述一点点乐谱基

10、础知识，我们就可以很方便地编辑这个数表了。比如音符“3”转换为“m3, t/4”，音符“3”转换为“m3, t/4+t/8”，等等。在music.c里，已经在数表myscore 里给出了乐谱化蝶开头一部分音符转换结果，其余部分请感兴趣的读者补充完整。程序清单1.10 timer pwm应用：蜂鸣器演奏乐曲文件：main.c #include systeminit.h #include buzzer.h #include music.h / 主函数（程序入口） int main(void) jtagwait(); / 防止jtag失效，重要！ clockinit(); / 时钟初始化：晶振，6m
